IEC 61850

ISO/OSI Model

Applicable Products

IEC 61850 is the most recent standard for communication networks and systems in substations. Its scope of definitions greatly exceeds that of the preceding standard IEC 60870-5-101. IEC 61850 comprises the these individual standards:

• IEC 61850-1, 61850-2
  Introduction and overview / Glossary
• IEC 61850-3
  General requirements
• IEC 61850-4
  System and project management
• IEC 61850-5
  Communication requirements for functions and device models
• IEC 61850-6
  Configuration description language for communication in electrical substations related to IEDs
• IEC 61850-7-1
  Basic communication structure for substation and feeder equipment - Principles and models
• IEC 61850-7-2
  Basic communication structure for substation and feeder equipment - Abstract communication service interface (ACSI)
• IEC 61850-7-3
  Basic communication structure for substation and feeder equipment - Common data classes
• IEC 61850-7-3
  Basic communication structure for substation and feeder equipment - Compatible logical node classes and data classes
• IEC 61850-8-1
  Specific Communication Service Mapping (SCSM) - Mapping to MMS (ISO 9506-1 and ISO 9506-2) and to ISO/IEC 8802-3
• IEC 61850-9-1
  Specific Communication Service Mapping (SCSM) - Sampled values over serial unidirectional multidrop point-to-point link
• IEC 61850-9-2
  Specific Communication Service Mapping (SCSM) - Sampled values over ISO/IEC 8802-3
• IEC 61850-10
  Conformance testing

IEC 61850 is not limited to the transmission format, but also defines a complete data model. It also introduces an XML-based language (Substation Configuration description Language -  SCL) offering a vendor-independent method of describing devices and their configurations.
